Timekeeping
This watch automatically adjusts its time setting in accordance with the time
calibration signal (Call Sign: DCF77) transmitted from Mainflingen, Germany. You can
also perform a manual procedure to set the time and date, when necessary.
Important!
• Before using the watch for the first time after purchasing it, use the procedure under
“To specify your time zone” to specify your time zone, and then perform the
procedure under “To trigger a calibration signal receive operation manually”.
• Time calibration reception is limited to specific geographic areas in West Europe.
Setting the Time and Date
There are three different methods you can use to set the watch’s time and date.
• Auto receive of the time calibration signal
• Manual receive of the time calibration signal
• Manual setting without using the time calibration signal
No matter which method you use, you must specify your time zone first (see below).
Specifying Your Time Zone
Use the Time Zone Mode to specify your current time zone. If you move to a different
time zone either inside or outside of the West Europe, simply change the time zone
setting and the watch adjusts its current time and date settings accordingly.
• See the “Time Zone Table” for information about time zones and applicable cities.
To specify your time zone
1.Use C to enter the Time Zone Mode.
2.Hold down B until the current time zone differential
value starts to flash, which indicates the setting screen.
• The time zone differential value indicates the number
of hours difference in time between the currently
selected time zone and UTC (Universal Time
Coordinated) in Greenwich, England.
Time zone differential value
3. Use A (+) and D (–) to change the time zone differential value.
4. Press B to exit the setting screen.
• If you are in an area that corresponds to the German time zone (1h) but does not
follow summer time (Daylight Saving Time or DST), select the time zone to the
west of the German zone. This means you would select the time zone with a time
differential of 0h instead of 1h in order to cancel the effect of summer time (DST).
Time Calibration Signal Reception
Removing the watch from your wrist and positioning it as shown in the illustrations
below helps to optimize signal reception.
• If your watch has a resin band, pass the end of the band through the band loop and
place the watch on a stable surface.
Note
See “Time Calibration Signal Reception Precautions” for important information about
time calibration signal reception.
Resin band Metal band
Pass through band loop.
To trigger a calibration signal receive operation manually
1.Use C to enter the Timekeeping Mode.
2.Place the watch on a stable surface to its top (12
o’clock side) is facing in the general direction of
Mainflingen, Germany.
• This puts the watch in the optimum position for time
calibration signal reception.
3.Hold down D for about three seconds, until the receive
indicator starts to flash, which indicates that signal
reception has started.
• Signal reception takes from two to five minutes. Take care that you do not move
the watch during this time.
• The receive indicator stops flashing and remains on the display when signal
reception is complete. The receive indicator remains on the display for three days
after a successful signal reception. The receive indicator does not appear if signal
reception is unsuccessful for some reason.
Receive indicator
• If the receive indicator does not appear when you hold down D, it means that
signal receive is turned off. Use the procedure under “To turn signal receive on
and off” to turn it on.
• To interrupt a receive operation, hold down D for about three seconds.
Switching between Standard Time and Summer Time
The time calibration signal sent from Mainflingen includes standard time and summer
time information. This means that if you are in an area that switches between summer
time and standard time on the same days as Germany, you do not need to make any
manual adjustments.
When you are in an area that does not correspond to German summer time and
standard time, you can use the following procedure to turn on summer time (Daylight
Saving Time or DST) and advance the current time by one hour, when necessary.
• Note that not all countries or local areas use summer time.
• If the watch receives a time calibration signal in an area that corresponds to the
German time zone, the time is adjusted in accordance with the time calibration
signal data. If you are in an area outside of Germany that corresponds to the
German time zone but does not follow summer time, you need to use the procedure
under “To specify your time zone” to select the time zone to the west of the time
zone where you are located.
To switch between standard time and summer time
1.Use C to enter the Time Zone Mode.
• Note that you cannot switch manually between
standard time and summer time while the time zone
differential setting is 0h, 1h, or 2h, and signal receive
is turned on. In this case, the DST On/Off setting does
not appear in step 3 below. Be sure to turn signal
receive off before switching between standard time
and summer time while the time zone differential
setting is 0h, 1h, or 2h.
2.Hold down B until the current time zone differential
value starts to flash, which indicates the setting screen.
3.Press C twice to display the DST On/Off setting screen.
• Each press of C moves the flashing in the sequence shown below to select other
settings.

4. Press A or D to toggle between standard time (oFF) and summer time (on).
• The DST indicator is on the display while summer time is turned on.
5. Press B to exit the setting screen.
• The summer time setting affects all time zones.
• The summer time setting does not affect UTC.
Calibration Signal Auto Receive
This watch is designed so that timekeeping accuracy is directly proportional to the
number of successful signal receptions the watch is able to receive (automatic gain
control). Because of this, we recommend that you always keep auto receive turned on
when you are within range of the Mainflingen transmitter.
• Auto receive is performed at 2:00AM German time each day, regardless of the
Timekeeping Mode time shown on the watch’s display. It is best to remove the watch
from your wrist and put it in a location where it can easily receive the signal prior to
2:00AM German time.
• The auto receive operation is performed everyday no matter what mode the watch is
in.
• This watch is shipped from the factory with auto receive turned on. You can change
the auto receive setting using the procedure under “To turn signal receive on and
off”.
To turn signal receive on and off
1.Use C to enter the Time Zone Mode.
2.Hold down B until the current time zone differential
value starts to flash, which indicates the setting screen.
3.Press C once to display the Signal Receive On/Off
setting screen.
4.Press A or D to toggle between Signal Receive (auto
and manual) on (on) and off (oFF).
5.Press B to exit the setting screen.
• If you use the above procedure to turn on signal receive,
the watch performs a signal receive operation (indicated
by the flashing icon) when you exit the setting screen in
step 5.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Return Features
If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically saves any settings you
have made up to that point and exits the setting screen.
Data and Setting Scrolling
The A and D buttons are used in various setting screens to scroll through the
available settings on the display. In most cases, holding down these buttons during a
scroll operation scrolls through the settings at high speed.
Timekeeping
• Home Time is displayed in 12-hour or 24-hour format, while UTC is always displayed
in 24-hour format.
• With the 12-hour format, the P (PM) indicator appears to the left of the hour digits for
times in the range of noon to 11:59 p.m. and no indicator appears to the left of the
hour digits for times in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, with 24
indicator.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all modes.
• The year can be set in the range of 2001 to 2098.
• The watch’s built-in full automatic calendar automatically makes allowances for
different month lengths and leap years. Once you set the date, there should be no
reason to change it except after you have the watch’s battery replaced.
UTC
The letters “UTC” stands for “Universal Time Coordinated,” which is the world-wide
standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks
that keep accurate to within microseconds. Leap seconds are added or subtracted as
necessary to keep UTC in sync with the Earth’s rotation. The reference point for UTC
is Greenwich, England.
Time Calibration Signal Reception Precautions
• This watch receives the time calibration signal (Call
Sign: DCF77) transmitted from Mainflingen, Germany
(located 25 kilometers southeast of Frankfurt). Signal
reception is possible within a radius of about 1,000
kilometers from the Mainflingen transmitter.
• Signal reception may be poor in the shaded area on the
map, even though it is within 1,000 kilometers of the
signal transmitter.
• The current time setting in accordance with the time
calibration signal takes priority over any time settings
you make.
• The Mainflingen time calibration signal includes summer
time (DST) data.
• The watch is designed to automatically update the date
and day of the week for the period January 1, 2001 to
December 31, 2098. Setting of the date by the time
calibration signal cannot be performed starting from
January 1, 2099.
• This watch can receive signals that differentiate between
leap years and non-leap years.
• Reception stops if an alarm starts to sound while the
signal is being received, and restarts after the alarm
operation is complete.
• Even when the watch is within the reception range,
signal reception is impossible if the signal is blocked by
mountains or other geological formations between the
watch and signal source.
• Signal reception is affected by weather, atmospheric
conditions, and seasonal changes.

• The time calibration signal is bounced off the ionosphere. Because of this, such
factors as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• This watch receives the time calibration signal transmitted from Mainflingen,
Germany. This means that reception is best when the antenna built into the 12
o’clock edge of the watch is facing towards Mainflingen. Note, however, that moving
the watch while the time calibration signal receive operation is taking place will make
stable reception impossible.
• Think of the watch as acting like a TV or radio when it is receiving the calibration
signal. When receiving indoors, move to a location as near as possible to a window.
Proper signal reception can be difficult or even impossible under the conditions
listed below.
Near TVs, refrigerators, computers, or other household appliances
Far away from broadcasting stations among ferro-concrete structures or near
mountains
Underground, in tunnels or in ferro-concrete buildings
Near high-tension wires, neon signs, or radio stations with interfering frequencies
Near railroads, highways or airports
In trains or cars
• Radio interference can make signal reception impossible.
• Strong electrostatic charge can result in the wrong time being set.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time with the precision noted in “Specifications.”
Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode, press L to illuminate the display for
about three seconds.
• The electro-luminescent panel that provides illumination loses power after very long
use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the battery life.
Low Power Battery Precautions
• The indicator ( ) on the display indicates normal battery power. The indicator
changes to a flashing when battery power is low.
• Though backlight, alarm, and signal receive operations are possible when the
indicator (
) is flashing on the display, you should avoid performing these
operations because they require high amounts of power. Have the battery replaced
by the store or dealer where you purchased the watch as soon as possible.
• Based on data as of December 2001.
